Silent: playback is stopped. Press play to start brown noise at 18 per cent.
- About 6 dB less energy every octave: the deepest of the three, closer to a waterfall or a distant engine.
- Silent. No audio node exists until you press play.
- 1.5 second buffers are generated and scheduled end to end, so the sound never comes round again.
- Playback fades out, then the audio nodes are disconnected.
Accuracy. The noise is generated in the browser from a random source, so it never loops and nothing is downloaded. White is equal energy per hertz, pink falls about 3 dB per octave and brown about 6, which is why brown sounds deeper. This is a sound generator: it makes no claim about sleep, concentration, tinnitus or any health effect.
Common questions
- What is brown noise?
- Brown noise has more low-frequency energy than white noise, so it sounds deeper and softer. The generator synthesizes it in your browser rather than streaming a recording.
- Can I play it while going to sleep or studying?
- You can use the playback, fade and timer controls for background sound. This audio generator makes no claim about sleep, focus or any health effect.
